Required RSA RADIUS Server Listening Ports
Required RSA RADIUS Server Listening Ports
RSA RADIUS is installed and configured with AM. All the RADIUS-related ports (1645, 1812, and 7082) on the AM server are open by default.
Note: You must protect these ports by blocking the ones that are not used and restricting access to the ones that must be used only by AM.
The RADIUS standard initially used UDP port 1645 for RADIUS authentication. The RADIUS standards group later changed the port assignment to 1812. The AM RADIUS server listens on both ports for backward compatibility. If all the RADIUS clients are configured to talk to the RADIUS servers only on ports 1812, you should block legacy port 1645 on the external firewall.
If you do not plan to use RADIUS, you can close the RADIUS authentication UDP ports 1645 and 1812.
